Embodiment Construction
[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0012] like figure 1 As shown, a printing and dyeing wastewater sludge treatment and reuse method, the production wastewater is concentrated into the adjustment tank, and the sludge in the final sedimentation tank is introduced during the process of the production wastewater flowing from the adjustment tank to the primary sedimentation tank, and the sewage generated in the primary sedimentation tank The mud is discharged outside, and the production wastewater continues to flow to the hydrolysis tank, the activation tank, and the secondary sedimentation tank for treatment, and then enters the contact oxidation tank, where chemicals are added to the contact oxidation tank, and then flows to the final sedimentation tank, where the production wastewater meets the standard and is discharged. The generated sludge is recycled and used in the treatment of the primary...
